AC SENSE RELAY Safe Power Sensing The AC sense relay provides isolated power sensing and control. It's more than just a relay in a box. It contains an AC powered relay, circuit breaker, safety delay and debounce circuits, and screw terminal dry-contact outputs. The relay coil driver senses AC power. The contacts can controls either AC or DC devices. Whenever AC power is within usable ranges (ie. 80-140VAC), the relay is activated. When activated, the NO contact is closed and the NC contacts is open. When power fails, this is reversed: NC is closed, and NO is opened. The output contacts are fully isolated, and can be directly connected to a microcontroller for signalling, or they can be used to control a high power AC or DC load. The two output contacts can control one normally on device, one normally off device, or both simultaneously. Applications include: • AC power failover systems • Battery / solar backup systems • . Building automation & home theater • Alarms, power failure alert systems. • Green power and energy conservation Loads of up to 15 Amps total may be controlled. Your imagination is the limit. • A single 120V AC input input signal controls one high-current SPDT relay. This relay signal switches a single contact which provides either normally-on or normally-off operation. • Self-contained design eliminates dangerous high voltage wiring and safety hazards. • Safety features include: Magnetic isolation -- eliminates shock hazard Relay hysteresis -- prevents relay chatter De-bounce protection -- extends contact life • The durable SPDT control relay is rated at 30/40A, 400,000 operations at 12A resistive. At no load, the estimated lifetime is 5.3 million mechanical operations. • A 15A thermal safety circuit breaker switch prevents overloads and adds supplemental protection. • Recommended operating ranges: AC input 90-120VAC. Current 0-12A. 15A peak. Stranded wire only. • Input connector: IEC 60320-1 C-8 • Output connector 3x screw terminals. • Included cord: 24" IEC-C7 to 5-15 unpolarized. • Indoor use only: -35F to 145F, 5-95% noncondensing.
